Doping of Ammonium Metatungstate usually involves the doping of a variety of elements, and the choice of these elements depends on the specific application needs and purpose. Below are some common doping elements and their related properties.
Rare earth elements
Rare earth elements such as cerium (Ce) nitrate, for example, are used to dope ammonium metatungstate to prepare rare earth doped tungsten nanopowders. This doping can affect the particle size and morphology of tungsten powders by limiting the polymerization of tungsten molecules through the process of gas-phase sublimation and redeposition, which prevents tungsten powders from becoming larger.
Transition metal elements
Transition metal elements such as magnesium (Mg), aluminum (Al), zirconium (Zr), titanium (Ti), etc. are also often used to dope ammonium metatungstate to improve the physical and chemical properties of materials. In lithium-ion batteries, tungsten doping can stably increase the operating voltage of the battery, increase the energy density, and improve the thermal stability of the cathode material.
Other elements
In addition to rare earth elements and transition metal elements, doping with other elements such as fluorine (F) may also be involved. The doping of these elements may be used to modulate the conductivity, thermal stability, or other specific properties of the material.
The type and concentration of doping elements have a significant effect on the properties of the final material. Therefore, when selecting doping elements, it is necessary to consider the application requirements of the material, the nature of the doping elements, and the doping process.
In addition, there are various preparation processes for doped ammonium metatungstate, including the sol-gel method, the grinding method, and the roasting method. The choice of these preparation methods also affects the distribution of dopant elements and the properties of the final materials. Therefore, in the preparation of doped ammonium metatungstate, it is necessary to select appropriate preparation processes and doping elements to obtain materials with excellent properties.
